G0592 Metal Cutting Bandsaw
The table shown in Figure 22 is a sampling of
speed rates for various materials. Use these as a
guideline.
The speed at which the saw blade will cut through
a workpiece is controlled by blade type
, feed rate,
and feed pressure. The feed rate is controlled by
two knobs on the control panel.
Note
: If a lubricant is used on the cut, the feed
rate can be increased by approximately 15%
.
To set the feed rate:
1. Raise the bow to the highest position.
2. Set the Feed Rate Dial
to the desired feed
rate. Range is from 1 being slowest, to 9
being fastest.
3. Turning the Feed Control Knob to the left to
lower the bow at the feed rate you have set.
Turning the knob to the right locks the bow in
position.
• If you get a tightly curled, warm shavings,
brown to black in color, you are using too
much downward pressure.
• Blue looking chips are from extreme heat
with a high band saw speed.
• Thin powder-like chips are from insuffi-
cient feed pressure. This will dull your blade
rapidly.
• The best cut and feed rate will give you
evenly shaped spiraled curls with very little
color change, if any at all.
